What is an annotation?

Annotation:

“a note by way of explanation or comment added to a text or diagram.”Synonyms: notation, comment, footnote; commentary, explanation.

Sometimes referred to as data labels or captions, annotations are often added to charts to add an extra layer of useful information for the reader. Think of it like using a highlighter on a block of written text. We can purposefully guide our readers to view certain aspects of the data that are important.

Why are they so useful?
